Abstract

This study proposes a water saving approach through the reuse of washing wastewater without draining. The final bath(neutralisation bath) of the washing processes for cleaning purposes is not drained but reused in the first step of the nextwashing process. All the practises are carried out in plant scale and by using actual operational data. It is found that 10-30%water saving can be obtained in washing processes without any investment cost. It is also observed that the method does nothave considerable negative effect on the quality of the fabric.
